"The Shisper glacier has moved 1,750 metres towards the villages in the last three months," the assistant director added. "Two power houses have closed owing to which 70% of Hunza's population has been rendered without electricity," he further said.

A portion of an under-construction power house has also been affected by the glacier surge.

The Shisper glacier has surged during the last six months and a huge supra-glacial lake has been formed which locals fear can burst or overflow causing extensive damage.
